A plastics crate for bottles has its base 14 formed with downwardly-extending ribs in closed formations to make stacking projections 46, 48, 50, 52 which can be engaged with the upper rim 22 of a like crate when stacked upon it, the ribs of the projections conforming to a ribbed lattice (36, 38), Fig. 1 (not shown), which constitutes the base. The projections 46 &c., Fig. 2, are so arranged that the crates may be stacked in aligned or crossed formation. Transverse walls 16, 18 separate the crate into compartments, the lower sections 44 of the walls being omitted and coinciding with rings (40), Fig. 1 (not shown), in the lattice of the base 14 to form holes through which broken glass &c. can pass when cleaning the crate. The projections 46 at the corners of the crate are provided with sockets (54) to receive rubber studs (58), Fig. 6 (not shown), which act as feet for the crate. Hand holes 24 are provided in the end walls of the crate. Vertical reinforcing ribs 30, 32 &c. are formed along the outsides of the crate, and internal reinforcing buttresses may also be provided. The reinforcing ribs 30 &c. are integral with an outwardly directed lip 20 having a lower surface which engages on the upper rim 22 around the top of the like crate below, when stacked upon it, to take the weight of the crate. In a modification. Fig. 3 (not shown), the stacking projections (70) are formed over parts of their lengths as continuations of a rib (68) extending right around the edge of the crate base 14; smooth passage of a loaded crate along a roller conveyer is thus obtained. Stacking projections (72), Fig. 4 (not shown), are then provided on the top surface of the upper rim 22 for engagement by the continuous base rib (68) of a like crate above. Alternatively, recesses may be formed in the upper rim 22 for the same purpose. To facilitate stacking of the crates upon their sides, sockets (74), Fig. 5 (not shown), are formed at rib junctions around the outer sides of the crate walls, to receive rubber studs (58), Fig. 6 (not shown). The studs (58) on one crate then engage in the sockets (74), Fig. 5 (not shown), in the adjacent crate. Alternatively, if it is desired to stack the crates on their sides out of alignment, three or more sets of slots (76), Fig. 7 (not shown), may be provided adjacent each end of the hand holes 24. One of the sets of slots is provided with a resilient pad for engagement in the slots of the adjacent crate. The side walls of the crate may be formed with windows.

Title: System for stabilising the position and size of a raster scanned by an electron beam on a target

Filed: 1968-11-20
Abstract: 1,242,126. Cathode-ray tube circuits. EIDOPHOR A.G. 20 Nov., 1968 [20 Nov., 1967; 4 Oct., 1968], No. 55168/68. Heading H4T. [Also in Division G3] An electron beam is scanned to form a raster which overlaps two electrodes arranged parallel to one another, one of the electrodes having two portions of different widths so that two sets of pulses are produced by interaction of beam and electrode for automatic stabilization of position and size of raster. In Fig. 1, an electron beam 8 is deflected by line and frame timebase generators 33, 35 associated with deflecting coils 32 to form a colour television raster which overlaps vertical electrodes 2, 3 on a target 1. Pulses produced when the beam traverses the electrodes are applied through an amplifier 9 to a pulse manipulator 42 which derives pulses f having a duration corresponding to the time taken for the beam to travel between the electrodes, and pulses s having a duration corresponding to the time taken to form that half of the raster adjacent that portion of electrode 2 which is wider and therefore produces wider pulses when traversed. The timing and duration of line pulses f are compared at 44 with the timing and duration of adjustable pulses o derived through a pulse manipulator 46 from line synchronization pulses applied at e. Logic circuits within comparator 44 produce duration error signals I and/or timing error signals K which are applied to line timebase 33 to maintain a desired width and horizontal position of the raster. The duration and timing of frame pulses s are similarly compared at 45 with the duration and timing of adjustable pulses r derived through a pulse manipulator 47 from frame synchronization pulses applied at v so as to produce error signals L and M which control frame timebase 35 to maintain a desired height and vertical position of the raster. The ends of the wider portion of electrode 2 are suitably sloped to avoid the production of a double pulse by a sloping line scan. Signals from frame timebase 35 are applied to modulate line reference pulses o to compensate for mechanical and optical trapezoidal distortion. If, on switching on, the raster fails to traverse one or both electrodes, pulse manipulator 42 is arranged to produce auxiliary pulses which deflect the beam until both electrodes are traversed and the normal control is effective. Separate control systems are provided for each colour.
